摘要： A reversible image display medium including two sheets; one or more developer accommodating cells formed between the two sheets, and each having a periphery surrounded by a partition wall; and dry developer contained in each of the cell(s), wherein the dry developer contains at least two kinds of frictionally chargeable dry developer particles having different chargeable polarities and different optical reflection densities. The image is displayed by forming a predetermined electrostatic field for each pixel in accordance with the image to be displayed and thereby moving the developer particles in a frictionally charged state. The image formed on the reversible image display medium can be erased, e.g., by an image erasing device.

摘要： A toner is formed on an image receiving sheet S. The image receiving sheet S has an irregular surface s2′ provided with continuous groove-like concavities R for accommodating toner. The toner T is removably adhered to the concavities R of the image receiving sheet irregular surface s2′ for forming the toner image. Ridges P extending along the continuous groove-like concavities R protect the toner T adhered to the concavities R. The toner image formation surface may be covered with a peelable protective sheet CF (CF′). When the image receiving sheet S carrying the toner image is to be reused, the toner is separated and removed from the image receiving sheet, and the image receiving sheet and/or the toner after removal of the toner are reused.

摘要： A method and apparatus capable of displaying a high-quality image using a reversible image display medium in which a cell(s) formed between two substrates accommodates at least two kinds of frictionally chargeable dry developing particles having different chargeable polarities and different optical reflection densities in image display, an electric field strength of, e.g., 0.3 V/μm to 3.0 V/μm is applied to the developer. An oscillating force (e.g. oscillating magnetic filed) is applicable and the oscillating force is substantially stopped during application of the electrostatic field. After completion of the electrostatic field, the surface of the medium on the image observation side may be charged to a potential holding the displayed image. Optionally, before image display, an alternating electric field may be applied to stir the developer for initialization of the medium.
